ATTACHMENT FOR IBEDSPRINGS.

Application filed November 19, 1921. serial No. 516,345.

mg is a specification.

This invention concerns bed-springs and relates more particularly to springs of that type wherein the mattress supporting fabric 1s mounted in. an open metallic frame having provision for supporting it upon a bedstead.

Such fabric supporting frames, as commonly. constructed, are of generally rectangular contour andfare'thus well adapted to fit snugly between the head and foot boards ofa bed-stead, leaving no appreciable portion of the mattress unsupported. When, however, such a frame is applied to a bedstead. of theso-called bow-end variety, wherein the foot-board, and sometimes the head-board, are outwardly curved or bowed, it is evident that a segmental space will be left between the straight end member of the spring frame and the curved end member of the bed.

Mattresses are commonly made long enough toextend within thebowed end of the bed,

but where the mattress overhangsthe straightend member of the spring frame it is unsupported and. tends to sag, thus detracting. very materially from the appearance of the bed when made up, while ifsuchsagging occurs at the head end of the bed discomfort to the user results. It thus. be-

comes desirable to provide a spring of such a shapeas to, fit snugly within a bow-end bed-stead whereby; properly to support the mattress, and one, object of the invention is to provide a spring frame applicable to a bow-.end bed and capable, when so applied, of supportingthe mattress throughout its entire extent. From certain considerations, it is desirable to retain theold, .rec tangularframe as a basls inthe construction ofaspringframe adapted for use with. a bow-end bed, as for exampleaby reason of the greater facility with which the mattress supporting-fabric ,maybe secured in such rectangular frame. Moreover, as the demand for. springs for bow-end beds is comparatively small as compared with the entire number made, it is more economical for the manufacturer to make up all of the frames of uniform pattern, while it mayin many cases become desirable for the user of an old style spring to convert it for use with a bow-end bed.

A further object of the present invention is therefore to provide an attachment, readily applicable to a spring frame of the usual, rectangular form, whereby such frame ma be made to fit snugly within a bow-end bedstead. The invention thus briefiy consists in general, in the provisionof a bed spring having a bowed end, or ends, adapted to fit snugly within a bow-end bed-stead, and in particular, in an attachment comprising a member having an outer curved or bowed contour and attachable to the straight end bar of an ordinary spring frame, such member preferably being so formed as to constitute an auxiliary open frame having chord-like elements extending from side to side thereof and constituting mattress supporting means. If desired, such elements may be secured at their ends to coil springs attached to the frame member of the attachment, in a manner similar to that in which the mattress supporting fabric is commonly secured to its rectangular frame, although the exact mode of securing such ele ments or the nature thereof is not an essential feature of the present invention.

In the accompanying drawings, there is illustrated, by way of example, one inode'of accomplishing the desired object, and in which,

Fig. .1 is aplan view of the device forming the subject-matter of the present invention showing the preferred form of thesame;

Fig. 2 is a similar view illustrating a modilied arrangement;

Fig 3 is a plan view of an ordinary bed spring having the device secured toone end thereof;

Fig. 4 is. a view similar to Fig. 3 but showing a bed spring provided at each end with one of said devices; and 7 Fig.5 s a transverse cross section on the line ab of Fig. 1 but to larger scale.

.Referring to Figs. 1 and 5, the frame of the device is illustrated as formed from angle iron comprising the horizontal flange 1 and the vertical flange 2. In making the frame a suitable length of such angle iron is bent at the points 3 and 1 respectively, adjacent its ends, to provide the end portions 5, 6, which extend substantially at right angles to the main portion of the device, it being understood, however, that such members may be curved throughout or partially straight as may be desired. To facilitate such bending of the angle iron, the horizontal flange member 1 thereof. may. be slit" as indicated at 7, or if desired a portion thereof may be entirely removed. A bowed frame is thus produced and extending between the end portions 5, 6 thereof is a supporting member 8 which may, if desired, be of resilient material, such for example, as a ribbon ofspring steel connected as by rivets 9 to the members 5, 6' respectively. At the free extremities of the members 5, 6, openings such as 20 are formed in the flange 1, such openings serving for the reception of bolts as hereinafter described.

In Fig. 3 there is illustrated a bed spring of usual? construction and of substantially rectangular form comprising the frame members 10, 11, 12, 13 respectively, to the end members 12, 13 of which are secured springs 14 serving to support the Wire mesh fabric 15 upon which the mattress rests. As illustrated in this figure, one of the attachmentdevices of Fig. 1 is shown as applied thereto, being secured to the end. member 13 by means of bolts 16 passing through. the openings '20 and through suitable openings in the end member 13. By thus securing the attachment to the ordinary rectangular spring frame, the latter is readily converted for use with a bow-end bedstead and without requiring any substantial change in the original form of the spring. The attachment may thus be appliedby the user of the spring, if desired, and also forms a con-' venient means whereby a manufacturer or dealer in bed springs may convert the ordinary spring for use with a bow-end bed in accordance with the demands of the trade.

In Fig. 1 arectangular. bed spring of usual. type is indicatedcomprising'the side members 10, 11 and the end members 12*, 13. respectively. In this case, however, the spring is shown as provided with bow end attachments at each end thereoflbeing thus suitable for use with a bedstead having both its head and foot ends bowed.

In either of the arrangements described, it willbe clear that the addition of the attachmentserves-to supplement the spring. frame proper by extending it into the space formed by the pro ection of the bow-end of the bed stead, while the supporting member Syserves to" prevent the saggingof' the mattress in such space. V

In Figt ithere is illustrated a modification of the device of Fig. 1 wherein the angle iron is illustrated ashaving the horizontal flange.

member 1 bent to form the side members 5 6*, respectively. In this case, however, in stead of the ribbon-like supporting member 8, a plurality of substantially parallel wires or equivalent devices 17, 18 are connected at their opposite ends by means of coil springs 19 to the members 5 6, respectively. If desired, these parallel elements may be connected by the members 21, thus forming a structuresubstantially similar to the spring structure of the main spring frame. The at tachment of Fig; 2 will obviously be applied to the spring frame in the same manner an" under the same circumstances as is the attachment previously described.

' While the structure hereinabove described is desirable in carrying the invention into effect, it is to be understood that various changes andv modifications might well be made therein 'without'departing from the spirit of the invention, For example, the frame of the attachment might be curved from. end to end, instead f'comprising a straight portion-merging into curved portions, it being understood that the term bow-shaped or bowed may well designateeither of such forms. Furthermore, it

is evident that if desired, the bed spring might be formed with non-detachable bow ends whereby certain of the advantageous results of. the present invention might ac crue. It is also; clear that material other. than angle iron might well be employed in forming the frame of the attachment, while other suitable supporting elements might be supplied for use with such frame 'whereby' to supplement the spring proper and to fill the space between the end members thereof to prevent sagging of the mattress.

Having thus described the inventionin a preferred embodiment ofthe'same, what I claim and desire to secure by Letters Patent of the United States is z 1.
